STATES A 'I' E FITTING FOR PNEU'llllIA'll'IlC-TIREl VALVES.

Application led Aug'ust 16, 1927, Serial N'o. 213,408, and in Australia April 5, 1927.

This invention relates to an improved retaining device cr holder for the valve cap ot a pneumatic tire valve.

Motorists and cyclists are well aware of the inconveniences and difficulties caused by the inadvertent loss of tire valve caps.

The present invention has been devised to provide improved devices which will effectively overcome these disadvantages.

In the accompanying drawings Figure 1 is a sectional view of a valve of a pneumatic tire equipped with the improved valve cap retaining device.

Figure 2 is a detail view of the retaining device for the valve cap.

Figure 3 is a sectional view of the clip device shown in Figure 2.

In these views 2 indicates the stem of a tire valve7 3 the valve screw cap and 4 the usual nut provided Jfor securing the valve to the wheel rim.

According` to the invention, I provide a valve cap retaining device 5 comprising a spring clip G of arcuate design adapted to fit around and embrace the valve screw cap 3 as shown in Figure 2. This spring clip 6 has downwardly extending legs 7 which are arranged one on each side of the valve stem, and they are pivotally connected at their lower ends to pins 8 carried by a collar 9. This collar is screwed onto the Avalve stem 2 so that it can be rotated simultaneously with and to the same degree as the valve cap 3.

The spring clip 6 is preferably serrated onV its inner surface to firmly grip the periphery of the valve cap 3, and, if desired, said clip may also be serrated on its outer surface, as is shown in Figure 6 whereby it can be conveniently rotated.

When it is desired to remove the valve cap 3v from the valve stem, the retaining device 5 and the valve cap are rotated until the said cap is unscrewed treek from the valve stem. The retaining device is now pivotally swung downwardly on the pins 8 as shown .in dotted lines in Figure 6, thereby allowing free connection ,of an inator or a connection from a compressed air tank and preventingmisplacement of the valve BERNARD SCHLEICHER.
